Description
|
|
-----------
|
|
|
|
Casts light in a 2D environment. A light is defined as a color, an energy value, a mode (see constants), and various other parameters (range and shadows-related).

Enumerations

|
------------
|
|
|
|
.. _enum_Light2D_ShadowFilter:
|
|
|
|
.. rst-class:: classref-enumeration
|
|
|
|
enum **ShadowFilter**:
|
|
|
|
.. _class_Light2D_constant_SHADOW_FILTER_NONE:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`ShadowFilter<enum_Light2D_ShadowFilter>` **SHADOW_FILTER_NONE** = ``0``
|
|
|
|
No filter applies to the shadow map. This provides hard shadow edges and is the fastest to render. See :ref:`shadow_filter<class_Light2D_property_shadow_filter>`.
|
|
|
|
.. _class_Light2D_constant_SHADOW_FILTER_PCF5:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`ShadowFilter<enum_Light2D_ShadowFilter>` **SHADOW_FILTER_PCF5** = ``1``
|
|
|
|
Percentage closer filtering (5 samples) applies to the shadow map. This is slower compared to hard shadow rendering. See :ref:`shadow_filter<class_Light2D_property_shadow_filter>`.
|
|
|
|
.. _class_Light2D_constant_SHADOW_FILTER_PCF13:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`ShadowFilter<enum_Light2D_ShadowFilter>` **SHADOW_FILTER_PCF13** = ``2``
|
|
|
|
Percentage closer filtering (13 samples) applies to the shadow map. This is the slowest shadow filtering mode, and should be used sparingly. See :ref:`shadow_filter<class_Light2D_property_shadow_filter>`.

|
|
:ref:`BlendMode<enum_Light2D_BlendMode>` **BLEND_MODE_ADD** = ``0``
|
|
|
|
Adds the value of pixels corresponding to the Light2D to the values of pixels under it. This is the common behavior of a light.
|
|
|
|
.. _class_Light2D_constant_BLEND_MODE_SUB:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`BlendMode<enum_Light2D_BlendMode>` **BLEND_MODE_SUB** = ``1``
|
|
|
|
Subtracts the value of pixels corresponding to the Light2D to the values of pixels under it, resulting in inversed light effect.
|
|
|
|
.. _class_Light2D_constant_BLEND_MODE_MIX:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|

:ref:`BlendMode<enum_Light2D_BlendMode>` **BLEND_MODE_MIX** = ``2``
|
|
|
|
Mix the value of pixels corresponding to the Light2D to the values of pixels under it by linear interpolation.
